This brush is awesome! The MAC girl was applying a shimmer powder to my face from the Rococo collection with this brush and it felt absolutely amazing & delicately soft unlike any brush I have ever felt. No joke!
She said the white part is make from fiber optic fibers.They did not mention goat hair which makes me somewhat mad, the website concludes that it is goathair.
Any ways this brush feels like butter and is super high quality.
A really expensive price (40.00)even so it is rather nice and ultra luxurious quality brush.
